Do you mean that you want to use the the graph it another program?
If so yes. In Rsudio you can click on the "Export" button in the Plots Window and save the plot or you can use the png() command ---see ? png--- to save the plot as an image that you can use in other programs such as LibreOffice or Word.
Here is a very simple plot that is saved to disc.
png("myplot")
plot(1:20)
dev.off()
